Reliability data analysis techniques - Procedures for comparison of two constant failure rates and two constant failure (event) intensities
Techniques d'analyse des données de fiabilité - Procédures pour la comparaison de deux taux de défaillance constants et de deux intensités de défaillance (événements) constantes
Specifies procedures to compare two observed - failure rates; - failure intensities; - rates/intensities of relevant events. The procedures are used to determine whether an apparent difference between the two sets of observations can be considered statistically significant. Numerical methods and a graphical procedure are prescribed. Simple practical examples are provided to illustrate how the procedures can be applied.
